The clutch arm needs to be in a nearly vertical (straight up) position when the clutch is fully at rest and the adjustment screw is against the stop. It may need to be rotated one spline, with corresponding adjustment to the slave's pushrod.
Can you get about 1.5mm (0.060") free play and have the clutch disengage completely? If so, drive the car 80 to 100km while making lots of shifts. Don't slip the clutch and don't make hard launches, just lots of shifting. This will wear off most of the "fluff" from the new disc, and should help. Then readjust the free play at the slave.
Or, you can just try the long throw slave, which will give you more "throw" right-out-of-the-box.
